Question

Hope someone can help me here. I use the daily login page that my ISP leads to the system and launches the Internet on my machine. It leaves several times between the connection and I am redirected to the login page. When you click the "Login" button, the Internet starts again.

My question is. Can I automatically detect if the Internet is disconnected and use a script that automatically logs me in.

The login button on the redirected page is as follows:

<input type="submit" name="Submit" id="btnSubmit" value="Login" onclick="return checking();" />
